Hi Bartosh, also re:

The primarily modeling strategy in MoI is totally different than that, it's about identifying key profile curves that define your shape and drawing those 2D curves, using some for building shapes such as with extrude or revolve and using others to cut pieces with boolean operations.

If you go through the tutorials in the manual you should see that's the process being used, there isn't any type of sculpting-like process like you're describing above.

But a lot depends on what type of models you are trying to create. If it's organic shapes like say the head of a warthog, then the sculpting method is a good approach for that (although with a long learning curve). So in that case you would not want to build that model in MoI, it would be a better fit for the poly modeling process. Most man-made type of objects are a very good match for the 2D profile curve driven approach though, those are the kinds of models that become awkward and time consuming to "sculpt" rather than "draw".
